If you do not want Applications Manager to generate alarm for the first time the threshold condition is crossed, then you can use this option to specify the number of consecutive polls before generating an alarm. For e.g., If you want an email alarm to be generated only if the CPU Disk utilization is above 100%, consecutively for more than two polls, then you can configure the number of consecutive polls before reporting an error as two. In Action / Alarm Settings , you can have a common setting for all the monitors.
If you want to overwrite the common settings, you can also configure the polls before reporting an error on availability and threshold of individual monitors.
To Configure Polls on Availability for Individual monitors
To Configure Polls on Threshold for Individual monitors
Note: Specify the number of polls that can be scheduled before reporting an error. By default, it takes the value from action / alarm settings. For e.g., if you have created a threshold for web server to be critical if the response time crosses 100 seconds. And you wish to receive an email alarm only if the web server becomes critical after two polls and not at the first poll itself. Then configure the number of polls before reporting an error as two. You can leave the 'Polls before reporting an error' field empty to have the action / alarm settings for consecutive polls to take effect.
